Chief Software Developer, Environment Operation
SimCorp A/S - Denmark
“We experienced very few problems and in general the
upgrades were very fast.
We were able to upgrade almost all of our 200+ database
instances to Database 12c with a downtime of only 30-40
minutes (and that includes some of the pre- and post-tasks).
I have been upgrading Oracle databases since 9i to 10g, and
this has been the best release (measured on how easy
upgrading is) so far."
